The electrode reaction of the nickel -hydride battery.deep cycle trolling motor battery company

  Corporation: Ni (OH) 2 + OH- → (←) NIOOH + H2O + E-φ (standard electrode potential) = + 0.49V

  Negative poles: M + H2O + E- → (←) MH + OH-φ (standard electrode potential) = -0.829V

  Total response: ni (oh) 2 + m → (←) niooh + mh

  It can be seen from the above response equation that the electrochemical reactions occurred during the charging and discharge process are all solid -phase transformation mechanisms. There is no intermediate soluble metal ion in the process, and there is no consumption and production of electrolytes, so The internal resistance of nickel -metal hydride batteries is not much different.

  Nickel -hydride battery is over -charged and reacted

  1. overcharge

  Corporation: 4OH- → 2H2O +O2 +4E

  Negative poles: 2H2O+O2+4E → 4OH-

  2. Excessive discharge

  Corporation: 2H2O +2E → H2 +2OH-

  Negative poles: H2+2OH- → 2H2O+2E

  In the process of overloading and discharge, due to the catalytic effect of hydrogen storage alloy powder, oxygen and hydrogen generated by the positive electrode can be consumed, so that the nickel -metalized battery has the ability to resist overcharge.

  At the end of the charging and overcharge, the O2 precipitated on the positive electrode can be diffused to the negative surface and the hydrogen compound through the diaphragm, which is restored to H2O and OH-into the electrolyte, thereby avoiding or reducing the phenomenon of increased pressure accumulation inside the battery. Otherwise, when the battery is over -charged, the MH electrode will generate a large amount of hydrogen, causing the internal pressure of the battery to rise; and at the time of discharge, the H2 precipitated on the positive pole can be quickly absorbed by MH through the diaphragm. When discharging, O2 will be used on the MH electrode, which will cause MH alloys to be oxidized.
